cheers, super. i am looking forward to getting the one or two "sticky" spots sorted so thomas can run at a slower speed. will be something for the new year i think.
yes, the spiral would be totally enclosed. it was covered up, which we removed as no one could get in to clean the rails etc. the only other access is from underneath, so derailments were hard to retrieve. we are considering a plastic dome to go over the top, but not sure yet.
this is what it looked like a few weeks ago...

the hoop is a tablet holder, i think bamboo? back before we had the automated signal system, tablets were used to ensure track clearance.
i have seen a version of it in action at a preservation group. they have double track at the station, which merges to one for the length of the track. they run 2-3 trains at a time, passing the hoop from driver to crewman. the crewman has to manually change the points to allow their train to proceed.
im not 100% sure how it worked in the good ol days, found this on youtube. similar idea,
another link i found compared it to the american block system, but superior to it. also found this on wiki... http://en.wikipedia.org/wiki/Tyer%27s_El...ain_Tablet http://www.valleysignals.org.nz/regulati...tregs.html
